Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-6The disc filter shown is easy to assemble and disassemble, including a filter housing 1, a connector 2 installed on the top of the filter housing 1, a filter assembly 3 arranged in the center of the inner cavity of the filter housing 1, the top of the filter assembly 3 fitting against the lower surface of the connector 2, an inlet pipe 4 embedded at one end of the surface of the connector 2, a drain pipe 5 embedded in the center of the connector 2, and the bottom end of the drain pipe 5 inserted into the inner cavity of the filter assembly 3. The filter assembly 3 includes a support frame 31, and filter plates 32 are placed in the inner cavity of the support frame 31 from bottom to top. The filter plates 32 and the surface of the support frame 31 at the upper end are provided with a disassembly and assembly mechanism 6. By providing the disassembly and assembly mechanism 6 on the support frame 31 on which the filter plates 32 are installed, the operator can quickly disassemble and assemble the filter plates 32 when replacing them, which improves the efficiency of the operator in disassembling and assembling the disc filter and saves the operator's disassembly and assembly time.

[0025] The disassembly and assembly mechanism 6 includes a fixing component 61. The lower surface of the fixing component 61 is in contact with the surface of the filter plate 32. Positioning rods 62 are fixedly connected around the top of the support frame 31. Positioning grooves 63 are provided on the surface of the fixing component 61 at positions corresponding to the positioning rods 62. The fixing component 61 is inserted into the positioning rods 62 through the positioning grooves 63. Positioning buckles 64 are engaged with the outer wall of the fixing component 61 at the upper edge of the support frame 31. The fixing component 61 can be in contact with the filter plate 32, thereby enhancing the positioning effect of the fixing component 61 through the positioning rods 62. The positioning buckles 64 can connect and fix the fixing component 61 to the support frame 31, making it convenient for staff to quickly replace and install the filter plate 32.

[0026] The fixing member 61 includes a fixing ring 611, and a pressure block 612 is fixedly connected around the inner ring of the fixing ring 611. The lower surface of the pressure block 612 is in contact with the surface of the upper filter plate 32. Through the cooperation of the fixing ring 611 and the pressure block 612, the position of the filter plate 32 can be limited.

[0027] The positioning buckle 64 includes two semicircular rings 641. One end of each semicircular ring 641 is connected by a hinge. The inner wall of the semicircular ring 641 engages with the outer wall of the support frame 31 and the fixing ring 611. The other end of each semicircular ring 641 is integrally formed with a fixing block 642. A positioning sleeve 643 is engaged with the surface of the fixing block 642. A slider 644 is fixedly connected to the inner cavity of the positioning sleeve 643 at a symmetrical position. A groove 645 is provided on the outer wall of the fixing block 642 at a position corresponding to the slider 644. The two semicircular rings 641 can wrap around the support frame 31 and the fixing ring 611 through the connection. Then, the positioning sleeve 643 on the fixing block 642 can fix the two semicircular rings 641 together. The sliding groove 645 and the slider 644 cooperate to form a pull-and-lock connection, which improves the efficiency of disassembly and assembly by the workers.

[0028] A fixing rod 7 is fixedly connected around the bottom of the inner cavity of the support frame 31. A fixing hole 8 is opened on the surface of the filter plate 32 at the position corresponding to the fixing rod 7. The filter plate 32 is sleeved on the fixing rod 7 through the fixing hole 8. The cooperation between the fixing rod 7 and the fixing hole 8 ensures that the filter plate 32 installed inside the support frame 31 will not rotate, thereby improving the positioning effect of the filter plate 32.

[0029] Support blocks 9 are fixedly connected to the bottom of the support frame 31. The lower end of the support block 9 is fixedly connected to the bottom of the inner cavity of the filter housing 1. The support blocks 9 can provide support between the support frame 31 and the filter housing 1, so that there is space between the filter housing 1 and the support frame 31. The bottom of the filter housing 1 is connected to the drain pipe 10. A control valve is installed on the surface of the drain pipe 10, and the internal flushing wastewater can be conveniently discharged through the drain pipe 10.

[0030] In practical use, the fixed ring 611 and the pressure block 612 work together to limit the position of the filter plate 32 and ensure it fits snugly against the filter plate 32. The positioning rod 62 enhances the positioning effect of the fixed ring 611. Then, the positioning buckle 64 connects and fixes the fixed ring 611 to the support frame 31. During the disassembly and assembly of the positioning buckle 64, the two semi-circular rings 641 connect and wrap around the support frame 31 and the fixed ring 611. Then, the positioning sleeve 643 fitted on the fixed block 642 fixes the two semi-circular rings 641 together. The sliding groove 645 and the slider 644 work together to pull and snap together, which facilitates the quick replacement and disassembly of the filter plate 32 by the staff, improving the efficiency of the staff in disassembling and assembling the disc filter and saving the staff time.
